1 WMO Global Atmosphere Watch – Task Team on Observational Requirements and Satellite Measurements as Regards Atmospheric Composition and Related Physical Parameters 2009 GAW Motivation: Research conducted on atmospheric composition accounting for the human impact on the atmosphere enables better services

2 2 The GAW Mission  Systematic Global Monitoring of the Chemical Composition of the Atmosphere.  Analysis and Assessment in Support of International Conventions.  Development of Air Pollution and Climate Predictive Capability

3 3 The GAW Programme Elements World Standard Dobson Spectrometer, Hawaii

4 GAW Forward Planning test footer 4 GAW Strategic Implementation Plan ( ) - within the context of WMO SP & CAS priorities WMO Strategic Plan , which can be summarized as «Science for service» and include: Disaster risk reduction Global integrated polar prediction system (GIPPS) Megacities Global Framework for Climate Services (GFCS) WMO Integrated Global Observing System (WIGOS) and WMO Information System (WIS)

5 5 GAW – What’s Next? Continue to improve observational systems and data processing to: + allow near real-time provision of GAW data, + support integration of surface, vertical profile and column datasets from different platforms to provide a unified understanding of aerosol and gas distributions, + minimize gaps in the measurement networks in data-poor regions, + support the service needs of megacities and large urban complexes, and + to track trends and support conventions and assessments.

6 Observational Requirements for GAW from a Satellite Perspective test footer 6 Our major tasks are to help GAW develop a strategy for the integration of satellite observations of atmospheric composition and related physical parameters into the GAW program & oversee the RRR for atmospheric composition. Identify priority applications/services/products for GAW Review WIGOS identified application areas needing composition information Review current and planned satellite mission wrt atmospheric composition Discuss framework for implementing the integration of the composition observations within the GAW SIP

7 Application Areas – Background (1) test footer 7 WIGOS Applications: Global numerical weather prediction (GNWP); High-resolution numerical weather prediction (HRNWP); Nowcasting and very short range forecasting (NVSRF); Seasonal and inter-annual forecasting (SIAF); Aeronautical meteorology; Atmospheric chemistry; Ocean applications; Agricultural meteorology; Hydrology; Climate monitoring (as undertaken through the Global Climate Observing System, GCOS); Climate applications; and Space weather. In addition, the observational requirements for WMO polar activities and the Global Framework for Climate Services (GFCS) are also to be considered under WIGOS.

8 Application Areas – Background (2) test footer 8 The IGACO document identified key research applications in atmospheric chemistry to be: air quality; oxidizing capacity; stratospheric ozone; and coupling atmospheric chemistry and climate.

9 Application Areas – Background (3) test footer 9 CAS-16, which identified six emerging areas: high impact weather; water; Integrated Global Greenhouse Gas Information System (IG 3 IS); aerosols; urbanization; and new technologies, including geo/climate engineering.

10 GAW SIP – “Research Enabling Services” test footer 10 SSC initially identified priority services as those related to climate, high impact weather, urban (air quality/health), ecosystems, and support of conventions.

12 Application Areas test footer 12 Ecosystem services/total deposition….

13 EPAC SSC  Kobus Pienaar, Fakulteit Natuurwetenskappe, Faculty of Natural Sciences, North-West University/ Noordwes Unversiteit, Potchefstroom, S.Africa  Karla Maria Longo, Institution: Center for Earth System Science, Group Modeling of the Atmosphere and its Interfaces (GMAI) at the National Institute for Space Research, São Paulo, Brazil  Paul Monks, Professor of Atmospheric Chemistry and Earth Observation Science, University of Leicester, United Kingdom  Melita Keywood, Stream Leader Aerosol Air Quality and Climate, Acting Research Group Leader Atmospheric Composition and Chemistry Centre for Australian Weather and Climate Research – A partnership between the Australian Bureau of Meteorology and CSIRO, CSIRO Aspendale, Australia  ZHANG, Xiao-Ye, Prof., Chinese Academy of Meteorological Sciences Beijing, CHINA 13

14 In addressing those priorities, GAW can contribute for example: Through observations, analysis and prediction of pollution episodes due to extreme weather events, like heat waves, or forest fires Through information on short-lived climate forcers in polar regions (including aerosol) Through megacities activities addressed by GAW and building upon GURME Through global observations of long-lived greenhouse gases and aerosols, that can be used as a tool for climate mitigation, which goes together with adaptation Through integration of different spatial and temporal scales that can be considered as a contribution to WIGOS test footer 14

15 15 GAW – What’s Next? Advance observations and analysis of chemical constituents of the atmosphere and UV radiation to help reduce environmental risks to society from high-impact weather and air pollution, and to mitigate the impacts of, and adapt to, changing climate.
